• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

Just clone the repo in ubuntu env and try to install the dep.

• What is the expected behavior?

After cloning the repo , npm install should install all the pkgs and it should allow us to run the app.

• Please tell us about your environment:

• nxplorer version: 1.5.6
• other environment details
  -node -8.12.0
  npm -6.4.1
  ubuntu 16

• Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. npm , github, stackoverflow etc)

This problem is not related to the project as if you see the project builds fine on Travis (Linux)

The issue you are facing is related to npm and npm install is not able to update the package-json.lock file

Possible solutions for you
npm install --no-package-lock
The --no-package-lock argument will prevent npm from creating a package-lock.json file.

or delete the package-lock.json file and then try

Thank you for posting this. I've been using Windows and travis seems to work. Will investigate

Can you'll update the version of node js to the latest instead of 6 and see it works. I'll get hold of a ubuntu machine to test as well . https://stackoverflow.com/questions/48739985/npm-err-code-z-buf-error-when-install
